Hello, I am repeating my request for help. My biggest problem is with unpacking and packing using the UEFI tool. Even when I don't make any changes, using Extract Body, Replace Body. It give me boot loop even without changes in bios just repacking... Can anyone recommend another program for editing this UEFI?
I have an HP Victus 16-s0117nq laptop and I want the bios logo changed (NOT THE OS ONE, don't reccomend using HackBGRT since it only changes the os logo). The BIOS is Insyde F.30 Revision A and the cpu is AMD.
Hi, bumping this old thread. All the Sony download links are now dead (removed in 2023/2024). I'm also looking for EP0000294663.exe (BIOS R1021C8) for my SVS1312C5E. Does anyone still have this file saved locally? Would really appreciate if someone could share it!
Thanks for sharing this. Does this tool work reliably on the HP EliteBook 8440p with BIOS F60, and is there any documentation or guide for using it safely? Also, does the patch require any special hardware beyond the CH341A programmer? Thanks.
Hi, and thanks for the interest! Yes - it's confirmed working on the 8440p with BIOS F.60. That's the exact version I hardware-tested: after flashing the unlocked BIOS, the laptop boots to Windows with a non-whitelisted Intel AX200 (Wi-Fi 6, ~560 Mbps). It also covers the other 8440p BIOS versions (F.22 / F.24), because the integrity-gate is located by code pattern, not a fixed offset. The single most important safety step - read this first: Before anything, dump your BIOS with the programmer and save that original file untouched as your backup. Then run the tool on a copy. The tool never modifies your original (it always writes a new *_unlocked.bin), but keeping your first dump safe means you can always flash it back if anything ever goes wrong. Safe-use guide (there's also a README.txt in the package): Read/dump your BIOS chip with the CH341A → save it - this is your backup. Open the tool → Browse to the .bin → Analyze (it tells you exactly what it can do, and it even detects an already-unlocked dump so you don't double-patch). Tick Remove Wi-Fi whitelist (and/or Remove BIOS password). Create → save the new *_unlocked.bin. Flash that new *_unlocked file back with the CH341A - make sure Verify passes. The tool also strict-verifies and refuses anything it can't positively confirm, so it won't produce a bad image for an unknown board. Hardware: nothing special beyond the CH341A - a SOIC-8 test clip (or the desoldered chip) is all you need. Everything else happens in software, on the dump. Good luck and again: keep that original backup!
